I wrote a simple nostr relay that can be accessed via a pkdns domain. It automatically creates a pkarr domain and publishes it on the DHT.

The goal is to be able to setup a relay without having to rely on ICANN which is a corrupt system. The relay's websocket URL looks something like this:

wss://9zbr9pp1pkpqdwugzny9o8uuo9yjenc1dxt6gwpwaqxg8qg5omxo

I'm a beginner in Rust but it runs :)
